WorldFish working together with the Bangladesh Institute of Development Studies has exposed evidence of aquaculture's link to poverty reduction in a new report. Data gathered over a ten-year period provides important evidence for the need to invest in the sector as a way to alleviate global poverty and hunger.
By analyzing changes in fish consumption in Bangladesh between 2000 and 2010, the report proves conclusively that...

INTRODUCTION Sustainable aquaculture depends upon eco-friendly and economically and socially viable culture system. The recycling of organic wastes for fish culture serves the dual purpose of cleaning the environment (by avoiding the problem of waste disposal) and providing economic benefit. The recycling of animal dung/wastes in fishponds for natural fish production is important to sustainable aquaculture and to reduce...

Both male and female gonads undergo marked cyclic morphological and histological changes before reaching full maturity and becoming ripe. This is called maturation of the gonads. Most of the fishes exhibit seasonal cycle in the production of gametes. The expulsion of gametes from the body into the surrounding water is called ‘spawning’ resulting in fertilization. Fish spawns during a specified periods of the year which coincides with the several...

The situation in the farming of the pangasius in Indonesia is very different from that in Vietnam, the world's largest producer of pangasius catfish. Three species of pangasius are reared in Indonesia, Pangasius hypophthalmus, P. sutchi, and P. jambal . Up to 3,000 small hatcheries and 12,000 small farms, which are located in West and East Java, Lampung, Jambi, Riau, Palembang and south Kalimantan, produce fish for local consumption. In 2008, 4 billion...

INTRODUCTION The gilthead seabream (Sparus aurata Linnaeus 1758) is a perciform fish, belonging to the family Sparidae and to the genus Sparus. It inhabits the Atlantic coasts of Europe, Mediterranean and Black sea (rare) and is one of the most important marine fish in fishery and aquaculture (especially in the Mediterranean area). Due to its euryhaline and eurythermal habits, the species is found in both marine and brackishwater environments...

Description of Freshwater Prawn Farming Freshwater prawns, Machrobrachium rosenbergii , or shrimp are currently popular with small scale aquaculturists in the southeasternUnited States. Pond acreage has been constructed in nearly all states, but particularly inKentucky,Mississippi,Texas,Tennessee,Georgia, andAlabama. Research atKentuckyStateUniversity has reported larger yields (Tidwell et al. 1999)...

INTRODUCTION Fish farming is expanding rapidly throughout the world and has a high potential for the provision of valuable protein in less developed countries (Little & Edwards, 2003). Due to global population expansion, demand for high quality animal protein, especially from aquatic sources, is rising. Increasing the aquaculture production is clearly needed to meet this demand in the third millennium,...

The brine shrimp Artemia is a small crustacean that can be found in saline waters in all over the world in natural habitats or commercial farms. The brine shrimp is a unique aquatic animal which is used in aquaculture systems (Bengtson & Sorgeloos, 1991). The Urmia Lake is one of the largest hyper-saline lakes in the world with a total surface area between 4750 km2 and 6100 km2 (Azari Takami, 1987; Eimanifar & Mohebbi, 2007); this...

INTRODUCTION According to GAFRD (2007) total fish production in Egypt was 1,008,008 tons where 635,517 tons were produced through aquaculture. Aquaculture represents 63.0% of the total fish production (Ahram, 2010). The mullet species represent about 30% of the harvest and considered as important consummated species. The expansion in Nile tilapia was also associated with the production of all male tilapia and since then...

ABSTRACT
The brine shrimp Artemia is important for aquaculture since it is bighly nutritious. It is also used widely in biological studies because it is easy to culture. The aim of the present study is to review the literature on the taxonomical nomenclature of Artemia. The present study indicates the existence of seven species: three living in the Americas, one in Europe, and three in Asia.

The cysts of brine shrimp Artemia are widely used in the aquaculture industry (Sorgeloos 1980, Sorgeloos et al. 1998, Sorgeloos et al. 2001). They are produced commercially by culturists in many places or harvested from their natural habitat, such as the Great Salt Lake (Van Stappen 2003). Irrespective of the fact that each species or population has its own unique characteristics, the processing of Artemia cysts is an important factor in price determination....

Introduction Pig production is one of the most important livestock sections in agriculture in the Mekong delta. Intensive pig farms and small scale farms have grown remarkably; in most cases, pig waste is directly drained to the water surfaces, resulting in severe environmental pollution. Realizing that problem, some waste bio-treatment methods have been applied to reduce environmental...

INTRODUCTION Cyanobacterial blooms in freshwater ecosystems have created serious water quality problems. These problems and their ecological consequences have been intensively studied in freshwater (Chorus and Bartram, 1999; Chorus, 2001; Adeyemi, 2009; Sahmoune et al., 2009; Khanna et al., 2009; Mishra et al., 2009; Banerjee and Srivastava, 2010; Adekunle et al., 2010). Harmful effects of cyanobacteria in fisheries, domestic and recreational...
